Add raw ZPL to label

[samvandamme]

Is there a possibility to add raw ZPL to a Zebra::Zpl::Label? I want to cache the zpl of an image to not recompile it every time. The image will always be on the same spot with the same attributes.

Thanks

Yes, this is possible. There is an undocumented Zebra::Zpl::Raw class that does just that. It's usage is very similar to other elements:

require 'zebra/zpl'

label = Zebra::Zpl::Label.new(
  width:         600,
  length:        305,
  print_speed:   6,
  print_density: 5,
  copies:        1
)

zpl_string = "^GFA,1300,1300,13,,::::::O01IFE,N01KFE,N0MFC,M03NF,M0OFC,L03PF,L0QF8,K01QFE,K03RF,K07RF8,J01SFC,J03F9OFE7E,J07F01MFE03F,J07E007LF803F8,J0FE003KFE001FC,I01FEI0FC00FC001FE,I03FCI04M01FF,I07FCQ01FF,I07FCQ01FF8,I0FFCQ01FFC,I0FFEQ01FFC,001FFEQ01FFE,:003FFEQ03IF,003FFEQ01IF,007FFCR0IF,007FFCR0IF8,007FF8R07FF8,00IFS03FF8,00IFS03FFC,:00FFES01FFC,01FFES01FFC,01FFES01FFE,:01FFCS01FFE,:::::01FFES01FFE,::01FFES03FFE,01IFS03FFE,01IFS03FFC,01IF8R07FFC,00IF8R0IFC,00IFCR0IFC,00IFEQ01IFC,00JFQ03IF8,007IF8P07IF8,007IFCP0JF8,007JFO03JF,003F87FCN0KF,003F81FFM03JFE,001F80FFEK01KFE,001FC07FFCJ0LFC,I0FF03FF8J0LFC,I0FF03FF8J07KF8,I07F81FF8J07KF8,I03F807F8J07KF,I03FC004K07JFE,I01FCN07JFE,J0FEN07JFC,J07FN07JF8,J03F8M07JF,J01FCM07IFE,K0FFM07IFC,K07IF8J07IF8,K03IF8J07IF,L0IF8J07FFC,L07FF8J07FF8,L01FF8J07FE,M0FF8J07F8,M01F8J07E,N07K038,,::::::::::::::^FS"

raw_zpl = Zebra::Zpl::Raw.new(
  data:       zpl_string,
  position:   [50, 50],
)

label << raw_zpl

zpl = ''
label.dump_contents zpl
puts zpl

Boom, thanks, that does the trick!
